2.84

僧問：「如何是學人自己？」師云：「老僧入泥入水。」僧云：「某甲粉骨碎身去也。」師喝云：「大海水在爾頭上，速道速道。」僧無語，師代云：「也知和尚恐某甲不實。」

A monk asked, "What is the student's self?" The Master said, "This old monk enters the mud and water." The monk said, "I shall powder my bones and crush my body." The Master shouted and said, "The water of the great ocean is over your head! Speak quickly, speak quickly!" The monk was speechless. The Master answered on his behalf, "I also know the upādhyāya feared I was not genuine."
